The invention discloses a vehicle, a driving range determination method thereof and a controller, and the method comprises the steps: determining the farthest initial position of the vehicle according to the current position of the vehicle, a preset driving direction and the current residual electric quantity, calculating the lowest energy consumption of the vehicle from the current position to the initial position according to the real-time road condition information, and determining the driving range of the vehicle according to the calculated lowest energy consumption. If the comparison result of the minimum energy consumption and the current residual electric quantity does not meet the preset condition, updating the initial position in the preset driving direction, returning to execute the operation of calculating the minimum energy consumption of the vehicle from the current position to the initial position according to the real-time road condition information until the preset condition is met, and executing the operation of calculating the minimum energy consumption of the vehicle from the current position to the initial position according to the corresponding initial position when the preset condition is met. And obtaining a drivable range of the vehicle in the preset driving direction. The driving range of the vehicle is determined in real time in the actual driving process of the vehicle, the mileage anxiety of a driver is relieved, and the driver can conveniently and reasonably plan travel, charging and other arrangements according to the driving range of the remaining electric quantity.

    本发明公开了一种车辆及其可行驶范围确定方法、控制器,该方法包括:根据车辆的当前位置、预设行驶方向和当前剩余电量,确定车辆最远到达的初始位置,根据实时路况信息,计算从当前位置至初始位置时车辆的最低能耗,若最低能耗与当前剩余电量的比较结果不满足预设条件,则在预设行驶方向上更新初始位置,返回执行根据实时路况信息,计算从当前位置至初始位置时车辆的最低能耗,直至满足预设条件,根据满足预设条件时对应的初始位置,得到车辆在预设行驶方向上的可行驶范围。实现了在车辆实际行驶过程中,实时确定车辆的可行驶范围,缓解了驾驶者的里程焦虑,便于驾驶者根据剩余电量的可行驶范围,合理规划出行和充电等安排。
